To aZZf/wiom may concern.'

Be it known that l, WILLIAM S. KrNsLnY, p a citizen of the United States, and a resident of Reading, in 'the county ot' Middlesex and State of Massachusetts, have invented an improvement in Cleaners for Fibrous `Stock and Methods of Uleaning llibrous Stock, of which the following description, in connection with the accompanying drawings, is a l0 specification, like characters on the-drawings representing likeparts.

rfhis invention pertains to improvements in cleaners Vfoi-*fibrous stock, methods'ofV cleaning such stock, and more particularly,

Vthough not exclusively, to improvements in clusters for and methods of cleaning wool.

In the drawings, which show an illustrative embodiment of a preferred form of my invention Y V Figli is a side elevation of a. preferred i form of duster with its cooperating feeding device; and

F ig. 2 is a sectional elevation through a portion of the feeding mechanism, through the more important portions of the dusting mechanism, showing details 'of a preferred embodiment of my invention selected for illustrative purposes. Y

ln the `drawings I have shown a feeder which preferably includes a hopper indicated in its entirety at 4 having in'one portion at the bottom thereof a slowly travelling conveyor 5 for conveying the stock in the direction of the spiked apron or elevator 6, which may resemble somewhat the usual Bramwell feeder, being provided with a rotary doctor 7 for knocking off from the spiked elevator any large lumps of stock which may be elevated thereby, and with a clearer 8, which assists in removing from the spiked elevator the stock elevated thereby which is to be fed to the duster.

The apron 6 is located in the hopper portion 4, this portion (as indicated in Fig. 1) abutting on'the line 4l the portion of the hopper containing the conveyor The iopper portions 4and 4 are separable on the line 4b so that the portion 4 may be assembled complete with the apron 6, the portion 4 may be assembled complete with the conveyor 5, and the hopper portions 4 and 4fL then placed in proper relation to each other and bolted or otherwise secured together. The separability of the hopper on the line 4b isalso of advantage in that, by

separating these portions of the hopper, ready access to the apron 6 0r conveyor is afforded for :replacement or repairs.

The feeder before-described preferably deposits the material in a hopper v9 Vcommunicating with al duster which preferably includes a casing fitting relatively closely about a rapidly rotated dusting element 10 having pins or other projections thereon l adapted to beat thematerial in the casing so that the dust may pass out through a screen 1l. The cluster is preferably provided with a discharo'e door 12 and a supply door 13,V preferably 'operated by automatic mechanism hereinafter more fully described.

rllie machine may conveniently be driven by a vpulley on the beater shaft 14, and means may be `pr vided on said shaft for driving the belts 15 and 16 supplying power to the doctor 7 and clearer 8.

l have found it advantageous to provide at one end of the shaft 14 a worm 17 meshing with a worm gear 1S on a shaft 19, which may conveniently supply power for driving the conveyor 5 and elevator G. l preferably mount on the shaft 19 means for automatically controlling the discharge door 12 and supply door 13` of the duster, and in the embodiment of my invention herein shown, this means'tf-ikes the form of the cam 2() adapted to rock a. bell crank 21, one end ofA which is coupled by a connecting` link 22 with a lever 25:3 secured to the shaft on which the discharge door 12 Vis pivoted. This cam operates the' opening ofthe door, the closing thereof being gravity-actuated, the weight ofthe door preferably being supplemented by a counterweight 24. To control the opening and closing of the supply door, l preferably provide a cain`25 on the shaft 19 adapted to rock a bell crank lever 26 connected by a link 27 to a lever 28 which in turn is connected to the supply door 13. The cam preferably actuates opening of the door, and the closing thereof is preferably yieldingly actuated as by a weight 29, which may be supplemented by a spring 30 on the connecting link 27.

rlhe timing of the door operating parts is preferably such that the supply door 13 will be closed whenever the discharge door 12 is open, so that at no time can material pass through the duster without having been dusted to a considerable extent.

While for some purposes and for some `grades of stock it may be better to supply v in closer proximity to the screen 11 and therefore to be very .thoroughly cleaned.

Where a batch of material is introduced substantially as a unit, some of the material WillV not have as good an opportunity as other portions thereof to be dusted in those portions ofthe beater adjacent the periphery thereof. I prefer, therefore, to so shape the door operating cams, that the supply door 13'Will remain open a very substantial portion of the time during which the discharge door 12 remains closed. The feeder includ- Y ing the elevator G and cooperating parts operates continuously so that, during the period when the discharge door is open and the .supply door closed, a comparatively small batch of material will accumulate on the top of the supply door 13 which will fall as a very small batch into the duster as soon as the discharge door 12 is open and the supply door 13 slid to the left by the operating mechanism. After this opening of the supply door 13, the material Will be fed to the cluster as discharged .from the feeder, and the material as itfenters will bey progressively subjected to the greatest cleansing action adjacent the periphery of the duster. As clearly appears from Fig. 2, the casing of the duster preferably lits relatively closely to the rotating part thereof throughout substantially its entire periphery. To increase the dusting action, stationary pins 31 are provided between the rotary pins on the duster drum 10, and to facilitate discharge the pins 31 are mounted on a roclrshaft 32, which carries the lever 21, so that when the discharge door is open the pins 31 Will be 'throivnupivardly somewhat, to provide a surface which will not materially obstruct the passage of the dusted material thereby.

While 1 have 'shown and described a pre-V ferred `form of one embodiment of my 1nvention, it will be understood that major changes involving omission, substitution, al-

tei-ation and reversal of parts, and even changes in the mode of operation, may be made without departing from the Vscope of my invention, which is best defined in the following claims. Y l

Claims:

1. fr cluster comprising, in combination, a rotary beating ele-ment, a Vcasing therefor including a screen at the bottom thereof, stationary beating means at one side thereof, aY discharge door at the opposite side thereof Yand a supply door at the top thereof.

2. Dusting apparatus comprising, in con bination, a beater casing, including a supplyV ing. doors for said openings, coordinated poiver means for opening and closing said doors at short intervals in such manner that onel is open When the other is closed, and means for feeding material to said supply door continuously and at such rate that all the material entering said casing when said supply door is open is subjected to dusting action close to saidscreen. Y

ln testimony whereof, l have signed my name to this specification.
